“…The emitted light will disappear when the excitation light turns off. The light generated under excitation light is called fluorescence, and the material that can emit fluorescence is called fluorescent material [7][8][9][10][11]. The nano thin film made of photo-luminescent material single-walled carbon nanotubes (SWCNT) can achieve precise measurement of micro-strain and has broad application prospects.…”

Monitoring the micro-strain on the surface of equipment is of great significance for its health monitoring and daily maintenance. A micro-strain detection method is researched in this article based on the photoluminescence characteristics of SWCNT materials. The detection of micro-strain can be achieved by using the SWCNT strain sensing film pasted on the surface of the tested equipment. A standard strain gauge can also be pasted on the back of the corresponding position where the SWCNT strain sensing film is pasted to check the detection accuracy of the SWCNT strain sensing film. A micro-strain loading device is designed in this paper. Then, a simulation study on the stress distribution of components with different shapes and sizes is conducted. Simulation results indicate that the geometric shape of the tested component has a significant impact on the stress distribution.

“…Printing technologies are an alternative to the above methods, which can considerably reduce the above limitations. Today, methods such as inkjet printing [ 51 , 52 , 53 , 54 ], aerosol printing [ 55 , 56 , 57 , 58 ], microplotter printing [ 59 , 60 , 61 ], microextrusion printing [ 62 , 63 , 64 ] and pen plotter printing [ 65 , 66 ] allow for the use of different types of inks (both true solutions and powder-based disperse systems) to form coatings of desired thickness and geometry on substrates of different natures. The above approaches are being actively developed in the context of obtaining materials for alternative energy, electronics, gas sensing, and optics.…”

The hydrothermal synthesis of nickel oxide in the presence of triethanolamine was studied. Furthermore, the relationship between the synthesis conditions, thermal behavior, crystal structure features, phase composition and microstructure of semi-products, and the target oxide nanopowders was established. The thermal behavior of the semi-products was studied using a simultaneous thermal analysis (in particular, using one that involved thermogravimetric analysis and differential scanning calorimetry, TGA/DSC). An X-ray diffraction (XRD) analysis revealed that varying the triethanolamine and nickel chloride concentration in the reaction system can govern the formation of α- and β-Ni(OH)2-based semi-products that contain Ni(HCO3)2 or Ni2(CO3)(OH)2 as additional components. The set of functional groups in the powders was determined using a Fourier-transform infrared (FTIR) spectroscopy analysis. Using microextrusion printing, a composite NiO—(CeO2)0.80(Sm2O3)0.20 anode film was fabricated. Using XRD, scanning electron microscopy (SEM), and atomic force microscopy (AFM) analyses, it was demonstrated that the crystal structure, dispersity, and microstructure character of the obtained material correspond to the initial nanopowders. Using Kelvin probe force microscopy (KPFM) and scanning capacitance microscopy (SCM), the local electrophysical properties of the printed composite film were examined. The value of its conductivity was evaluated using the four-probe method on a direct current in the temperature range of 300–650 °C. The activation energy for the 500–650 °C region, which is of most interest in the context of intermediate-temperature SOFCs working temperatures, has been estimated.

“…For material selection, several types of semiconductors have potential for use in large-size, low-cost, and low-power TFT devices with printing methods, such as metal oxide materials [13,14], organic semiconductors [15,16], and carbon nanotubes [17,18]. In contrast, inorganic oxides have appealing properties, such as environmental and electrical stability, element ratio adjustability, and transparency, which are required for printable driver devices [14,19].…”

Printing technology will improve the complexity and material waste of traditional deposition and lithography processes in device fabrication. In particular, the printing process can effectively control the functional layer stacking and channel shape in thin-film transistor (TFT) devices. We prepared the patterning indium gallium zinc oxide (IGZO) semiconductor layer with Ga, In, and Zn molar ratios of 1:2:7 on Si/SiO2 substrates. And the patterning source and drain electrodes were printed on the surface of semiconductor layers to construct a TFT device with the top contact and bottom gate structures. To overcome the problem of uniform distribution of applied voltages between electrode centers and edges, we investigated whether the circular arc channel could improve the carrier regulation ability under the field effect in printed TFTs compared with a traditional structure of rectangular symmetry and a rectangular groove channel. The drain current value of the IGZO TFT with a circular arc channel pattern was significantly enhanced compared to that of a TFT with rectangular symmetric source/drain electrodes under the corresponding drain–source voltage and gate voltage. The field effect properties of the device were obviously improved by introducing the arc-shaped channel structure.
